NTK VV0047 Engine Variable Valve Timing (VVT) Solenoid

NTK VVT Solenoid for Subaru Applications

The NTK Engine Variable Valve Timing (VVT) Solenoid VV0047 is a direct-fit engine control component for select Subaru models, including WRX STI, Impreza, Forester, and Legacy applications. Built with a black connector, blade terminals, a metal housing, and a female connector design, it supports precise oil control for variable valve timing systems.

NTK, The Sensor Specialist, brings OE-focused sensor and actuator coverage to the aftermarket. Backed by more than 80 years of automotive experience, NTK technical sensors are validated through thermal shock, vibration, and OBD verification testing to meet or exceed OE specifications.

Key Features

• Part number VV0047 for select Subaru VVT applications
• Metal housing for engine-bay durability
• Black female connector with 2 blade terminals
• 1 mounting hole for OE-style installation
• Engine Variable Valve Timing (VVT) solenoid / oil control valve design
• OE-focused coverage for import and domestic technical sensor applications

Detailed Description

NTK VV0047 is an engine variable valve timing solenoid engineered for Subaru engines that rely on accurate oil flow control to manage cam timing. It is listed for 2010-2021 Subaru Forester, Impreza, Legacy, and WRX STI applications, including models noted with an oil control valve. If you are searching for a Subaru WRX STI VVT solenoid, Subaru Impreza oil control valve, or a Subaru Forester variable valve timing solenoid, VV0047 is the relevant OE-style replacement reference.

This part cross-references Standard Ignition VVT172 for the same application.

What It Helps Address

• Check engine light related to VVT or cam timing control
• Rough idle caused by inconsistent oil control to the cam phaser system
• Reduced engine response from delayed valve timing adjustment
• Timing-related drivability concerns on Subaru Forester, Impreza, Legacy, and WRX STI models
• Oil control valve performance issues tied to variable valve timing operation

Installation Notes and Tips

Verify the connector style, terminal count, and mounting point against the original part before installation. Confirm the vehicle application by year and model, especially on 2010 Subaru Forester and 2010 Subaru Impreza builds noted from 1/6/2010, as well as 2011-2013 Forester, Impreza, and Legacy applications that include an oil control valve.

For best results, inspect the engine oil condition and related VVT passages during service. A clean oil supply is important for proper solenoid operation and consistent cam timing control.

Quality Assurance

NTK technical sensors are developed from OE experience and tested under thermal shock, vibration, and OBD verification conditions. VV0047 is manufactured to meet or exceed OE specifications for the listed Subaru applications.
